IMPROVEMENT IN HEATING AND VENTILATING REGISTERS.

Specification forming part of Letters Patent No. 67,355, dated August31, 1875); application filed August 13, 1875.

To all whom it may concern;

Be it known that I, JOHN B. OLDERSHAW, of Baltimore city, State ofMaryland, have invented a new and Improved Heating and VentilatingRegister; and I do hereby declare that the following is a full, clear,and exact description of the same, reference being had to theaccompanying drawing forming a part of this specification, in whichFigure 1 is a front elevation; Fig. 2, a central vertical section; Fig.3, a detail of the flue-stopper, with extensible portion.

The invention relates to certain improvements in heating and ventilatingregisters.

In all cases where it is desired to heat one or more rooms above, fromfire-place heaters, ranges, furnaces, or stoves, making the chimney-fluethe heat-conductor to the rooms above, it becomes necessary to stop offthe chimneyfiue above the register with a perforated fluestopper, thesmoke'pipe closing the aperture in the flue-stopper to prevent the heatfrom passing out at the top of the chimney, thereby diverting the heatand passing the same through a register, for the purpose of heating theroom in which the register is placed.

The method is now to cut a hole in the chimney-jamb sutticiently largeto receive the register, put into the chimney a perforated piece ofsheet-iron with flanges turned down, press itup above the aperture madefor the register, and nail it through the flanges to the sides of thechimney, adjust the pipe through the fiue-stopper,-put in the register,and fasten it with cement. As there is no opening in the chimney-jambabove the register, therefore there is no way of examining the pipesabove, or cleaning the soot from the fluestopper, only through theaperture of the same after the pipe is removed.

My devices are so constructed and arranged that the flue-stopper can beadjusted without nailing, and be removed at pleasure, exposing to viewthe top, bottom, and pipe immediately above and below the flue stopperwithout inconvenience, and also ventilate the room in which the registeris used.

The invention will first be fully described, and then pointed out in theclaims.

the room to be warmed. G is an extensible portion of the flue-stopperplate, which is attached to the latter by means of slides and guides at,and by means of which the said fluestopper plate may be adjusted to thedifferent-sized chimney-fines. K is a pivoteddetent for holding theextensible portion stationary, for which device binding-screws may beused. H is an adjustable cap, provided with lugs or extensions 1), whichfits into an aperture in the front vertical plate just above theflue-stopper plate. The lugs of this cap are inserted in the slots 0 cof the plate, and the cap being turned the hole in the plate is closed,and the cap locked. The object of this opening is to give ready accessto the upper part of the flue-stopper, for the purpose of cleaning outthe soot and examining the connections of the smoke-pipes. I arerevolving catches or buttons, which fasten the detachable register F insuch a manner as to admit of its being taken out for the purpose ofexamining the smoke-pipes below the fluestopper plate. J is an air-fluerunning around the edge and attached to the front plate A. Said flue isemployed for ventilating purposes, and opens into the room near thebottom through holes (I, regulated by a cutoff or slide, 6, and into thechimney-flue above the fluestopper at f.

Having thus described my invention, what I claim as new is 1. Thecombination of the front plate A, having flanges G (J, with theflue-stopper plate D, as and for the purpose described.

2. The combination, with the flue-stopper plate 1), of the front plateA, having the detachable register F, and the detachable cap H, as andfor the purpose described.

3. The combination, with ,the flue-stopper plate D, of the'fr'ont plateA,haviu,g thezventilating-flue J, opening into the chimney-flue above,and into the room below, substantially; as described.

4. Dhe combination, with the chimney-flue and register, of the fluestop'pe'r plate, having an extensible and adjustable portion, G, to adeptgit to 'differenesized flues, substantially as described.
